I give it a few days to see if an answer comes and if so, what it is before truly forming my own opinion, which if no answer comes might in essence not be so different than the one you expressed, just friendlier so. ☺I read it as a garden variety marketdroid troll, asking it specific questions is about as useful as trying to have a conversation with a cold-calling phone bot.
These masks were discussed here at length a couple of years ago. They are very dangerous, a potential death trap. They cannot be removed instantly upon surfacing as with a snorkel, and have any number of possible complications. I described these problems when the masks were first reviewed, as did many others. They are a marketing gimmick that promises to assuage the fear of submersing one's head but in reality they put the user's life at risk, especially a user likely to panic. The basic idea is more than 50 years old. They were dangerous then and remain so.Either of you care to elaborate? Not trolling, I have no financial interest in the product, but what is your concern about the design?
Clearly this is aimed at people who are less comfortable breathing through a mouthpiece than we all are. There have been snorkeling deaths with traditional equipment, as well as choking episodes, panic, etc...
I can see issues with CO2 related to dead space ventilation, but the devil is in the details and the design. Apparently there is an original and a knockoff - maybe there is the difference with regard to that particular issue.
But I don't see any reason to reject something out of hand that none of us have tried...

I have no information about mortality data, which in any case is difficult to establish, even with closed circuit systems. Drowning is a cause of death that frequently has undetermined prior contributing factors. I did try one of the high priced versions of these things last year and found them confining and complex. I wondered, while using the device, about what would happen if the mask flooded and I were faced with removing it quickly. I might be OK, but then I'm not afraid of the water and can control panic reactions.Has that ever happened (a death from one of these masks)? Not being snarky, just wondering.
Seems like a lot of non-divers use them and have no problem taking them off if there is a leak, at least in my personal experience. I mean, people who are not comfortable in the water can drown just by swimming, but as far as these bing a death trap, is this conjecture or data? Also, the newer models do seem different from the older ones.. not sure if those improvements are relevant.

A good fitting mask and snorkel has the virtue of virtually foolproof simplicity. The full face masks are not that easy to remove instantaneously, and disaster may take only a single gulp of water. A snorkel should be in the snorkeler's mouth, not an integral part of the mask. You can spit out a snorkel but removing a multi-banded mask in the event, however unlikely, of mask snorkel failure may be another matter entirely. An inexperienced person might have difficulty even understanding that the mask should be removed.
"So no actual reports of deaths or other issues while using these things." Where did you get that from? This discussion included mention of at least one death while using the device. Other accidents have been reported, though I have no details beyond what I read.OK, so no actual reports of deaths or other issues while using these things. There is plenty of CCR mortality data available.
Again, not saying that it's a good idea or a bad idea, but I think that we shouldn't call something a "death trap" based on conjecture, when there aren't any actual instances of a death on this units happening that we can point to, at least none that implicate the gear itself.
As tridacna said, pretty easy to take off. Can we come up with a scenario where someone who is terrified of the water swims out into rough conditions, aspirates, panics and drowns? I guess so, but that's not a reason to dismiss the idea out of hand when it seems to work well for it's target demographic.
As I might have mentioned, my wife, who can barely bring herself to take a single breath off of a regulator standing in the shallow end of the pool, called this a "game changer". So it might be worth looking into.
